Health care versus non-health care businesses' experiences during the 2009 H1N1 pandemic: financial impact, vaccination policies, and control measures implemented.

Background: Only limited data are available on businesses' experiences related to the 2009 H1N1 pandemic in terms of interventions implemented, staffing shortages, employees working while ill, and H1N1 vaccination policy.

Methods: A questionnaire was administered to human resource professionals during May-July 2011 to assess US businesses' experiences related to the 2009 pandemic. Logistic regressions were used to describe factors associated with providing H1N1 and respiratory hygiene training and offering H1N1 vaccine to staff.
